Application filed Apr112, 1914. Serial No. 828,969.

To all whom it may concern:

Be it known that we, ANTON J. Ammaorrr and JOSEPH Wnssnn, citizens ofthe United States, residing at Lindsay, in the county of Platte andState of Nebraska, have invented certain new and useful Improvements inFarm Machinery; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates broadly to farm machinery and has particularreferences to that class of machines which are known as pulverizers.

As a principal object this invention contemplates the provision of apulverizer which shall combine in one machine, means capable ofaccomplishing work usually intrusted to a number of machines now in usesuch as the ordinary form of disk pulveri'zer, stalk cutter, and harrow.

A further object isto provide a farm machine of the type described whichmay be used for renderlng a field even and smooth by pulverizing orgrinding the upper surface of the ground and at the same time cuttingand intermixing therewith the stumps of corn stalks previously plantedin the field.

A still further object is to provide a machine of this character whichshall be readily thrown out of engagement with the ground when it isdesired to transport the machine from place to place such as from thebarn to the field without causing its operation.

A still further object is to provide a pulverizing roller adapted foruse in connection with this machine which shall be driven by certainconnections with the drive wheel and which shall have connection withmeans for engaging or disengaging such driving connection.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification and then more particularly pointed out in the claim whichis appended hereto and forms a part of this application.

With reference to the drawings, wherein we have illustrated thepreferred embodiment of our invention as it is reduced to practice andthroughout the several views of which like characters of referencedesigtherefor,

nate similar parts, Figure 1 is a side elevational view of our machineas a whole, part of the tongue connected therewith, however, beingbroken away, Fig. 2 is a longitudinal section through our machineshowing in diagram, the operation of certain coacting parts, Fig. 3 1s afragmentary detail showmg the manner in which the blades or teeth of thepulverizer are connected thereto, Fig. 1 1s a sectional view of thematter shown in Fig. 3, such section being taken on the line 44 of thatfigure, Fig. 5 is an enlarged front elevation of the clutch mechanism asused 1n connection with our machine and, Fig. 6 1s a top plan view ofthe matter shown in Fig. 1, parts being broken away.

Proceeding now to the description of the drawings and having particularreference to Figs. 2 and 6, it will be seen that the main or bodyportion of our machine consists of the substantially rectangular frame10 suitably braced by the transverse beams 11, positioned adjacent-eachend'of the frame 10. The wheels 12, upon which this machine is adaptedto "travel are rotatably mounted upon the stub axles 13, which are inturn su1tably,mounted in the bearings 14, carried by the frame 10, andthe cross beams 11. A second rectangular frame member 15, is supportedby the frame 10 in the manner clearly shown in Fig. 2, both of theseframes being preferably formed from U-iron as at 16 in that figure.

Mounted in brackets 17, carried by the cross beams 11, and similar tobrackets 11 also carried by said cross beams is positioned thetransverse axle 18, to which the tongue 19 of the machine is pivoted bymeans of a suitable bracket 20. This tongue 19, is supported andreinforced by the bracing bars 21, which are loosely mounted upon theaxle 18 at one end and rigidly secured to the tongue 19 at their otherextremities.

A platform seat 22, is carried by the frame 10 by means of supports 23,so that the driver or operator of our machine shall have ready access tothe controlling means such means being hereinafter more fully described.At the two rearward extremities of the lower frame 15, we have providedthe caster wheels 2-i suitably journaled as at 25 in the bifurcated arms26, said arms carrying the threaded upstanding member 27 which isprovided with the hand wheel 28 for adjustment and is adapted to passthrough the frame 15 and to be adjustably secured therein. Suchadjustment as will be readily seen upon reference to the drawings caneasily be. made by rotatin the hand wheel 28 in the direction calculateto produce an upward or downward movement of the rear portion of theframe 15, which ever may be desired and also includes the suitable locknut 29 by which the member 27 is removably secured in any desiredadiusting position.

Further controlling means adapted to operate upon the frame members 10and 15 and designed to provide for the engagement or disengagement ofthe pulverizer to be hereinafter more fully described includes the handlever 30, pivoted at 31 to segmental rack 32 and connected by means ofthe link 33 to a bell crank 34, which ispivoted at 35 to the ear 36which is formed integrally with the rack 32. This bell crank 34, ispivotally connected by the link 37 to the ear 38, carried on the forwardportion of the frame 10.. It will readily be seen that a forwardmovement of this lever 30 from the neutral position shown in Fig. 2 willengage the pulverizer even more deeply with the ground surface and lowerthe rear portion of the frame 15 and that a backward movement of thelever 30 will have the reverse efi'ect of elevating said rear portion ofthe frame 15 and consequently disengage the pulverizer from contact withthe ground.

The customary locking means 39 operated by the usual hand grip 40, havebeen provided for this lever 30, in order to holdit in the positiondesired by the driver.

Commg now to the description of the pulverizer member proper asindicated at 41 as a whole it will be seen upon reference to Fig. 6 inwhich this portion of our invention is most clearly shown that aplurality of disks 42, are provided with the spokes 43, which connectwith the hub of said disks, the latter being rigidly attached to a shaft44 so that'the disks rotate therewith. Semi-circular recesses areprovided in the outer periphery of these disks at spaced intervals inwhich the pipes 45 are adapted to seat and in which they are secured bymeans of the bolts 46. The teeth 47 which are adapted to be carried bythese I pipes 45 are formed with the flange 48 which is curved toconform with the outer circumference of said pipes and are held rigidlythereagainst by means of bolts 49.

The shaft 44 carrying the above described disks is rotatably mounted ina suitable bracket 50 which depends from the frame 15 adjacent itsrearmost extremity. This shaft also carries upon its outer ends thesprocket wheels 51 which are adapted to be driven by means of a chain 52by the larger sprocket which is attached to the stub shafts 54. Theseshafts 54, are journaled in the ends of the frame 10, and the crossbeams 11,

anism so that the vehicle may travel without operating the pulverizer.The means for accomplishing this object include the double hand lever 59pivoted at '60 to the segmental racks 61, and provided with the usuallockin means 62 for'holding the lever in either of its positions.Pivotally connected to this lever 59 at points equidistant from thepivot 60, one above and the other below are the links 63 and 64 whichare connected at their other ends with yokes 65 loosely mounted on theslidable sleeve 66 which is provided with the customary teeth 67 forvmeshing with similar teeth formed in the loosely mounted collar 55.

It has been thought best in connection with the driving mechanism foroperating the pulverizer of our machine to provide a suitable chaintightener as is illustrated in Fig. 1, of the drawings. This tightenerincludes the bracket 67 secured to the frame 10 in the manner shown andadapted for use with the threaded shank 68 which is bifurcated at itslower end to rotatably receive the'wheel 69. The upper portion of thisshank is provided with the hand wheel 70 and it will be apparent thatrotation of this hand wheel will result in a downward movement of theshank and consequent tightening of the chain 52. It has also been foundhighly desirable to provide some sort of cleaning means for the teeth 47of the pulverizer in order that'this machine may continue to do its workin an eflicient manner. The cleaner which has been adopted. for use inconnection with this invention is shown in Figs. 1 and 6 and consists ofthe spaced teeth 71 which are connected to the rear member 72 of thelower frame 15 in an obvious manner and as will be seen afford areliable means for removing clods, stalks and other material which maybe impaled by the teeth 47.

The operation of our farm machine will be readily apparent from theforegoing de tailed description it only being necessary to bear in mindthat the adjustment of the rear caster wheels 24 and of the chaintightening wheel 69 is designed to be made before the machine is putinto actual use upon the field so that when the machine is so being usedthe driver or operator has but to so manipulate from his seat 22, thelever 30 and 59 as circumstances may dictate.

While in the foregoing we have shown in the drawings and described inthe specification such combination and arrangement of elements asconstitute the preferred embodiment of our invention, we desire toemphasize the fact that we may make such minor j changes in the mattersof proportion and degree, in later adaptations of our device as shallnot alter the spirit of our invention as defined in the appended claim.

What we claim is:

A machine of the class described, comprising a frame, drive wheelsmounted within said frame, a pulverizer mounted in the rear end of saidframe, a tongue pivotally mounted centrally of said frame, a segmentalrack bar arranged upon said tongue in proximity to the forward end'of'said frame, a bearing arranged upon the base plate of said rack of saidframe, whereby to actuate the for ward; end of said frame for raisingand bar, a bell crank lever revolubly mounted lowering said pulverizerat the rear end of.

said frame. i
